VEHICLE-HUB.

SPECIFICATION forming part of Letters Patent N 0. 670,480, dated March 26, 1901.

Application filed August 9, 1900. Serial No. 26.418. (No model.; I

To @ZZ whom t may concern:

Be it known that we, JOHN W. KELLY and EDWARD J. KEENA, citizens of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Vehicle-Hubs; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

The purpose of this invention is to materially cheapen and simplify the construction of hubs'designed chiefly for vehicle-wheels without detracting from their durability, efficiency, and appearance.

The hub is composite in nature,and is composed of metal and fibrous material so combined as to secure lightness, strength, and lasting qualities essential in devices of this nature.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the appended description and drawings hereto attached.

While the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a side view of a hub having the spoke-sockets in the same plane. Fig. 2 is a view similar to Fig. 1 of a hub having the spoke-sockets set staggered. Fig. 3 is a longitudinal section on the line O O of Fig. l, showing the spoke-sockets in position. Fig. 4 is a section on the line A B of Fig. l, showing some of the spokes in place. Fig. 5 is a section on the line N O of Fig. 3.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.` Y

The hub consists of a metal shell 1, a tapering metal box D, and fibrous filling-pieces F F', interposed between the end portions of the boX and shell. The center portion of the shell is thickened, as shown at M, and is provided with spoke-sockets 2, which may be arranged in the same plane, as shown in Figs.

tended bearing against the sides of the spoketenons R, so to brace them laterally. In the'formation of the shell care is to be exercised in the provision of the iianges 3, so that a slight space will be left between their inner ends and the box D to enable the latter to be forced home and thefllling-pieces F F to be bored without injury to the tool by coming in contact with the inner ends of any .one of the said flanges, which would be the case if left projecting inward too far. The iianges 3, besides bracing the inner ends of the spokes S, also strengthen the shell 1 in addition tothe thickened portion M. The outer ends of the spoke-sockets are enlarged, as shown at H, to receive the enlarged portion of the spoke adjacent to the tenons R.

The filling-pieces F F may be of any fibrous material, preferably wood, and are forced into the end portions of the shell l until their inner ends bear'irmly against the flanges 3. The wooden pieces are solid blocks of wood turned so as to snugly fit within the end portions of the shell and are subsequently bored in the usual manner, so as to receive the boX D. In the manufacture of spokes the length of the tenons vary and the present 'construction of hub admits of the spokes being driven home into the hub without any regard to the variation of length of the tenons, since the inner ends of the spoke-sockets are open.v After the spokes have been driven home and the lling-pieces F F forced into the end portions of the metal shell the hub is bored in the usual manner, so as to receive the boX D. The boring of the hub trues the inner ends of the spoke-tenons, as will be readily comprehended, and enables the spokes to obtain a seat at their inner ends upon the box D, as shown most clearly in Figs. 3 and 4.

Having thus described the invention, what is claimed as new isfl. In a vehicle-hub, a metal shell provided intermediate of its ends with a series of spoke-openings and having inner flanges in IOO line with said openings and formingV extensions of the walls thereof and acting jointly therewith to form sockets closed on all sides, the outer ends of which sockets are of larger extent eireurnferentially than their inner ends, which latter receive the spoketeuons, fibrous filling-pieces jr'oreed into opposite end portions of the shell against the end flanges of the sockets, and an axle-box fitted into a bore oi' the fibrous iilling-pieces and closing the inner ends of the spoke-sockets, substantially as set forth.

2. In a vehicle-hub, a metal shell having its middle portion thickened and formed with spoke openings and having` inner flanges forming extensions of the Walls of the spokeopenings and acting therewith to provide spoke-sockets closed on all sides and enlarged at their outer ends eireumferentially and shouldered intermediate of their inner and outer ends, fibrous Iilling-pieoes forced into opposite end portions of the shell against the end anges of the sockets, the inner ends of the spokes being trued simultaneously with the boring of the fibrous filling-pieces, and an axle-box secured in the bore of the fillingpieces and closing the inner ends of the spokesoekets, substantially as set forth.

In testimony whereof We affix our signatures in presence of two Witnesses.
